Laparoscopic Pancreaticoduodenectomy

The patient is positioned in French position (right arm in, left arm abducted 90°), with a suprapubic area reserved for Pfannenstiel incision. A 6-port technique is used: sub-umbilical (12 mm), four semi-circular trocars (two 12 mm, two 5 mm), and a sub-xiphoid trocar for liver retraction. Laparoscopic pancreaticoduodenectomy (LPD) proceeds if no vascular invasion/metastasis is found. Key steps include Kocher's maneuver, vessel ligation (gastroepiploic, gastric, gastroduodenal), lymphadenectomy (stations 5-17), pancreatic neck transection, and jejunal division. Reconstruction involves duct-to-mucosa pancreaticojejunostomy (or invaginating if duct unfound), hepaticojejunostomy, and stapled gastrojejunostomy. Margins are examined post-resection. Harmonic scalpel/Ligasure and staplers are used.
